September 2001
Rosemount Analytical Inc. A Division of Emerson Process Management System SIO Module 4-9
Model NGA 2000 Platform
Operation mode
Normal: The absolute measurement
signal will be sent to the analog output.
Adjust 0V: Used to set the display equal
to the analog output for 0V and 0 mA. Life
zero signals (4-20 mA and 2-10V) are set
automatically and cannot be adjusted.
Adjust 10V: Used to set the display
equal to the analog output for 10V and 20
mA.
Select the “Fine adjustment for 0% out-
put” and/or “Fine adjustment for 100%
output” lines with the ↵ or → key. Adjust
to the desired value with the ↑ or ↓ key
and confirm with the ↵ key. The range of
values are:
3000 to 4800 for 0% (default 4096)
750 to 900 for 100% (default 819)
The last three lines of the “Analog Output
Setup” menu are display only for configu-
ration values of the analog output.
Signal name: The name of the signal
chosen in the “Choose signal” menu.
Current signal value: The current value
of the variable.
Source module: The name of the mod-
ule Chosen in the “Choose signal source
module” menu.

Press More… (F5) key to change to the sub
menu Special Scaling for Concentration

This menu allows for the setting of each of
the 8 outputs to be the same as the range
limits “Yes” or as set on the previous menus.
See appropriate Analyzer module manual for
the range limits.
Press More… (F5) to change to sub menu
Analog Output Updates per Second.
This menu allows for the setting of the
update rate for each of the 8 outputs.
(If the Analyzer module does not allow the
setting of update rate, the lines will display
the fixed rate.)
